Hi Mark, perhaps I’m being dense but I’m having trouble figuring out exactly how you need it to sound. Do you need a regular, steady beat like a metronome ie. at the beginning of every second there is a tick, then another tick gets added at the half second, then another gets added so that the ticks sound at thirds of a second, then another is added so they sound at the quarter seconds? Or are you after an irregular beat as if, for example, you used footage of a clock (with sound) and you speed ramped the footage?
